This cover doesn’t need to be subtle or vague; all it needs to do is set up the fight that every fan had been waiting for: the Hulk against the Thing. These were Marvel's two heaviest hitters at the time, so it was only natural that they would eventually brawl.

The front page of Fantastic Four #12 sets up the premise of the book but also leaves readers wondering what happens next. Jack Kirby always did a great job at creating suspense by perfectly crafting covers that depicted the moments before an epic encounter. By not drawing the fight itself, Kirby kept fans in constant suspense until they plunked down money for the issue.
